Abstract

PURPOSE:To make it possible to cope sufficiently with strong rotational vibrations relatively-high in frequency by constituting a coupling body, connected to a diaphragm, by a hollow body and then by reinforcing this coupling body by a reinforcing method. CONSTITUTION:On the back surface of diaphragm 11, coupling body 29 is bonded perpendicularly at its center position P1. Free end part 29a of this coupling body 29 is supported by supporting method 31, e.g. damper 32. Then, distance l2 between free end part 29a and diaphragm 11 is set much longer than distance l1 between damper 15 supporting voice coil bobbin 13 and diaphragm 11. As a result, rotational vibrations of diaphragm 11 in the direction of arrow (a) or (b) are converted into those of coupling body 29 in the direction of arrow (c) to prevent rotational vibrations of rotary disk 11 securely. Further, coupling body 29 is composed of a hollow body and reinforced by a reinforcing body to improve rigidity against inflection and torsion. In consequence, coupling body 29 can be vibrated following accurately up diaphragm 11 and it is made possible to cope sufficiently with rotational vibrations high in frequency.
